I dont care if its 1 shot 1 kill but it shouldnt be 400 shots 1 kill nonetheless. Hard mode should make enemies detect you easier and make them do more damage. But the sthealth shouldnt be just grab/kill. When you are in stealth and headshot a person with suspenser he should die not turn to you and just kill you HE JUST GOT A BULLET IN HIS HEAD FOR GOD SAKE.
